LEAD-PENCIL.

SPECIFICATION forming part of Letters Patent No. 264,564, datedSeptember 19,1882.

I Application filed June 21, 1882. (No model.)

My invention has reference to a lead-pencil the sheath of which is woodand contains two kinds of lead-as, for instance, a redlead and a bluelead.

It has been usual heretofore, in making a pencil of this kind, to makethe sheath of two longitudinal pieces of wood the required length of thepencil-one or both grooved on their interior opposite faces forreceiving the lead. Then to put in the lead-groove the two sepa. ratesticks of lead, each filling about one-half the length of the groove,and subsequently to glue together the two pieces of wood and to finishthem up into pencil shape. This way of making the pencil is inconvenientfor several reasons, and offers besides a manifest obstacle to theoperation of varnishing and coloring the finished sheath. It isdesirable to color red that portion of the sheath that contains the redlead, and to color blue that portion which contains the blue lead, andso for other colors; but in producinga party-colored sheath it isdifficult, if not impossible, to prevent the two colors from blendingalong the line where they meet, thus giving the pencil an unfinishedlook and detracting from its appearance. operation of coloring thepencil is thus made diflicult and expensive, as well as uncertain. Ihave devised a pencil in which these difficulties are completelyobviated, and in which the line of separation between the blue and red,or between other different colors, is sharply defined. It can best beexplained by reference to the accompanying drawings, in which- Figure 1represents the two parts of a blank of a size fitted for the productionof six pencils. Fig. 2 represents in sectionalside elevation my improvedpencil.

The finished pencil consists of two half-pencils, A B, the formercontaining a lead, a-say red leadand the latter containing a separatelead-say blue lead. These two half-pencils are placed together end toend,in which position their aggregate length is that of a stand- Theardpencil, and are united by a pin or dowel, c, which enters and is gluedin holes bored in the meeting ends of the two parts. iug united orfitted together each half-pencil A B is colored and finished, so thatnothing further remains to be done to them after they are unitedtogether. posed oftwo parts permanently united into one pencil by adowel or pin connection, which is interposed between the two leads, andconstitutes a firm and permanent bond of union.

The pencil thus made is strong, and will withstand ordinaryusage withoutdanger of breaking. The pin or dowel may be of wood or any othersuitable material.

' The preferred way of making thispencil is The pencil thus is com-Before beas follows: The slabs C D used in their manufacture are of thesame size as used for ordinary pencils. They are usually of a size tomake six pencils, and for this purpose are provided on their interioropposite faces with six leadreceiving grooves, d, which register whenthe two slabs are put together. The grooves in the ordinary manufactureof pencils are filled with sticks of lead extending the length of theslabs; but in making my pencils I put in'each groove two separate piecesor sticks of lead, e, each of which is less than half the length of thegroove, and I interpose between their interior opposite ends a soft-woodplug or core, f. After this is done the upper slab, O, is fitted downupon the lower one so as to cover the lead, and the two are gluedtogetherin the usual way. Indeed, the leads are glued in the slabs, andthe latter are glued together in the manner usually practiced in themanufacture of wooden pencils; The object of the wooden cores is toproperly space the leads, and to prevent this portion of the groove fromfilling up with glue, which would oifer an obstacle to the afteroperation of boring the holes for receiving the connecting dowel or pin.The slabs, after being glued together, are divided lengthwise into sixpencils in the usual way.'

It is more convenientto fill each slab or set of slabs with leads of thesame color- For instance, the slabs G D would contain blue leads andanother set of slabs would contain red leads. The six pencils thusproduced are colored, varnished, and finished in theusual wayhaving ablue color, for instance. Each then is divided crosswise by a cutthrough the middle of its wooden core finto two half-pencils. Eachhalf-pencil is then bored out at the end which contains the portion ofthe wooden core so as to remove that core. A dowel or pin is fitted andglued into the hole thus bored, the

creased expense, a party-colored pencil, which is as strong for allpractical purposes as the ordinary wooden pencil, and which possesses afinish which it is not practicable to obtain in ordinary pencils of thiskind.

1 remark that in some cases there may be interposed between the two endlead-containing sections an intermediate section united with each of theend sections by a pin-and-socket connection. This, however, wouldmanifestly be an equivalent of the construction preferred by me andhcreinbefore described.

What I claim as new and of my invention 1s The herein-describedparty-colored lead-pencil, consisting of differently-colored woodensections, inclosing each its own colored lead, and united permanentlytogether, in the manner and by the means substantially as hereinbeforeset forth.

In testimony whereof I have hereunto set my hand this 9th day of June,1882.
